PHP - Recursion Question

It's not usual I ask questions on here - I usually help rather than be helped but alas, this is really confusing  !

Short Story (You can skip this to "Your Mission")
Without going into unnecessary detail i'll try to explain what i'm trying to do;

Take an array (example provided...) Array(
// These must be here, they are initially read by the template parser to get a starting point.
"data"=>Array(
"template"=>"main", // Template to start from (base template)
"content"=>"%custom_topmenu% <Br/>Table<Br/> %bigtablecustom1%", // replace %content% tag,Shows 2 Examples, A Custom Menu, and Main Table with Smaller Tables inside
),
// Below is numerically indexed arrays of content that will replace tags in the above "content" item
0=>Array(
"data"=>Array(
"rkey"=>"%bigtablecustom1%", // MUST have this item
"template"=>"bigtable_single", // MUST have this item
0=>Array(
"%title%"=>"Some Table Heading",
"%footer%"=>"Some Table Footer Message (author?)",
"%content%"=>"Some Content for the table with another rkey: %smalltablecustom1% --- %smalltablecustom2%",
"%title_note%"=>"Some Time and Date"
)
),
0=>Array(
"data"=>Array(
"rkey"=>"%smalltablecustom1%",
"template"=>"smalltable_single",
0=>Array(
"%title%"=>"Small Title",
"%content%"=>"Some Small Content or Note"
)
)
),
1=>Array(
"data"=>Array(
"rkey"=>"%smalltablecustom2%",
"template"=>"smalltable_single",
0=>Array(
"%title%"=>"Small Title 2",
"%content%"=>"Some Small Content or Note"
)
)
)
)
1=>Array(
// The menu is dynamically created by the module using it's inherited protected methods.
"data"=>Array(
"rkey"=>"%custom_topmenu%",
"template"=>"custom_topmenu",
0=>Array(
"%item1_name%"=>"Sub-Link 1",
"%item1_link%"=>"#",
"%item2_name%"=>"Sub-Link 2",
"%item2_link%"=>"#",
"%item3_name%"=>"Sub-Link 3",
"%item3_link%"=>"#",
"%item4_name%"=>"Sub-Link 4",
"%item4_link%"=>"#"
)
)
)
)
Turn this array into a single document, basically collpase all items with their children in the parent code.
The Problem (You can skip this to "Your Mission")
Now to make it easier and to (try) to prevent cross-tag contamination (so templates dont replace content that is supposed to be there from other template files...) I have wrote a recursion function that fills out all the content and removes the content sub-array from the data arrays (half the job).

So now I have a multi-dimensional array that needs collapsing into a single document (variable), I am getting confused with how to go through this array (below - not above) so that all the template items are "inserted" inside their parent array items.

The Function I made   
// Recursive, goes through an array and converts any "data" into actual templates. (Puts the content into a template)
private function parse_template_data_array($array){

// First let's count how many items are in the array that was passed to us
$item_count = count($array);

// This should never happen, each array should have at least a "data" array inside.
if($item_count < 1){
// Template Parser Fatal Object Syntax Error
exit("FATAL PARSER ERROR1");

// If there is only one item, we don't need to recurse (There are no "child" elements) and so we skip the recursive section.
}else if($item_count == 1){
// No items to parse, move on

// So there are some child elements we must recurse through.
}else{
// So this loops each "Child" element and passes that array to this function (recurse), Once it's finished it saves the array (result).
for($i=0;$i<($item_count-1);$i++){ // -1 from the count, 1 to get rid of the data array.
$array[$i] = $this->parse_template_data_array($array[$i]);
}
}

// This part does the initial "template expansion", it finds the template needed for this item and saves it with the content to this item.

// So we count how many data items we have
$dcount = count($array['data']); // Count Data Items (minimum of 2 - Each data array must have "rkey" and "template")

// If there isn't at least two items then someone made a booboo.
if($dcount < 2){
// Template Parser Fatal Object Syntax Error
exit("FATAL PARSER ERROR2");

// Otherwise let's sort this content out (We don't check if we only have the 2 minimum items since templates might not have Tags to replace).
}else{
// Load Template file using the "template" item in the data array.
$template = $this->get_file($array['data']['template']);

// Count the amount of data items (content) to replace tags inside the loaded template (If there is no content sub-array then put to 0 to skip the below part).
$dstrcount = (isset($array['data'][0]))? count($array['data'][0]) : 0;

// No template content, maybe no tags, just give the template content back.
if($dstrcount < 1){
// No items to parse

// We have some content to replace.
}else{

// We need the keys of the content sub-array so we can use (a neat feature of) the str_replace function.
$akeys = array_keys($array['data'][0]);
$template = str_replace($akeys ,$array['data'][0],$template);
}

// Save the result into this array item so we can pass the whole item back (This is also what happens when it recurses above)
$array['data']['content'] = $template;
}

// Return the result array.
return $array;
}

The Array returned by the above function

Your mission
(Should you choose to accept ofc ), is to take the above array and turn it into a single html variable, with all the child elements inside their parent templates by replacing the tags in the array. All the data required is in the array, all that is needed is to "collapse" the array.

Things to bear in mind:
%cdb_res_tpl_blk% - This is in the original template file, so the result of a successfull collapse will replace this tag with the result. Dont worry about this one [rkey] - This is the "Tag" to replace in the "parent" content. [template] - This is the template file. [content] - This is the content that needs to go inside the parent item.
Expected Result
<html><head></head><body>"Sub-Link 1"=>"Sub-Link 1",
"#"=>"#",
"Sub-Link 2"=>"Sub-Link 2",
"#"=>"#",
"Sub-Link 3"=>"Sub-Link 3",
"#"=>"#",
"Sub-Link 4"=>"Sub-Link 4",
"#"=>"#"<br />"Some Table Heading"=>"Some Table Heading",
"Some Table Footer Message (author?)"=>"Some Table Footer Message (author?)",
"Some Content for the table with another rkey: "Small Title"=>"Small Title","Some Small Content or Note"=>"Some Small Content or Note" --- "Small Title 2"=>"Small Title","Some Small Content or Note"=>"Some Small Content or Note""=>"Some Content for the table with another rkey: %smalltablecustom1% --- %smalltablecustom2%",

I will be working on this myself and if I find a solution I will post here. It is just that the way I code is I put my idea in my head, then try to code it in my head categorically, but when I think I find a solution it seems there is a bug, such as it will only collpase the main element, the bigtable, and the first small table, it wont do the other small table and not the menu either so basically it doesnt recurse items in the same array, only those underneath it. I'm so close but yet...so far...

THANK YOU for ANY light you can shed on this situation it's been bugging me for a few days now (admittely have not coded since my first attempt - so tired.)

My Code
I won't provide the code I've done for it now since it just flat-out doesn't work, I've lost the code that I mentioned earlier that was bugged I modified and to be perfectly honest can't be bothered to reproduce it (it won't get me anywhere).

Hello all,
I'm trying to change the way the output look like from Recursion
instead of it looking like this


and make it look like this





here is my code

Code: [Select]
<?php
$user = $_GET['id'];
echo '<hr>'; 
function display_mptt($user) {
global $db;
$id = $_GET['id'];
// retrieve the left and right value of the $root node
$sql2 = "SELECT * from mptt where id= ".$id."";

$result2 = mysql_query($sql2 ,$db);
if(!$row2 = mysql_fetch_array($result2)) echo mysql_error();
echo '<h1>Your Tree</h1>';

// start with an empty $right stack
$right = array();

// now, retrieve all descendants of the $root node
  $sql = "SELECT * from mptt WHERE `left` BETWEEN ".$row2['left']." AND ".$row2['right']." ORDER BY 'left' ASC";
 $result = mysql_query($sql ,$db);

 // display each row
  while ($row = mysql_fetch_array($result)) {
  // only check stack if there is one
  if (count($right)>0) {
  // check if we should remove a node from the stack
  while ($right[count($right)-1]<$row['right']) {
  array_pop($right);
  }
  }
 // display indented node title
 
 // add this node to the stack
  $right[] = $row['right'];
  }
  echo str_repeat('&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;',count($right)).$row['title']."<br>"; 
} 
  
  display_mptt(1);

?>

when in a form, I wish to build a conditional that if the response to a radio button is a value of 2 (female), it will display an input requesting for users maiden name. If not 2 goes to the next input statement.

Here is code I was experimenting with:


<html>
<body>
<form action="" name="test"  method='POST'>
<input type="radio" id="sex" value=1 checked><label>Male</label>
<input type="radio" id="sex" value=2><label>Femaleale</label>

    <?php
    $result = "value";
    if ($result == 2)
        echo "<input type='int' id='gradYear' size='3' required>";
        else
        echo "Not a female!"
    ?>

    <input type="submit" value="GO">
</form>
</body>
</html>


The code passes debug, however, Not a Female is displayed.

My question is - Can I do this and if so, what value do I test against id='sex' or value. I tried each one but gave the same results. I realize that $_POST[sex] would be used after the submit button is clicked. But this has me stumped.

Thanks for the assis in advance.

I'm trying to secure my login system as much as possible from SQL injections and other attacks. I know that by using mysql_real_escape_string() you can prevent that and I'm using that on for example the username input, but I would like to know if you hash the password before you send it to the database with MD5, do you still need to use mysql_real_escape_string()?

A very quick and simple example:

Code: [Select]
<?php

$un = $_POST['username'];
$pass = $_POST['password'];
$pass = md5($pass);

mysql_query("SELECT * FROM users WHERE password='$pass' AND username='$un'");

?>

If someone wrote a possible SQL query in the password input, wouldn't that be rendered useless as the md5 will hash it before sending it and therefor "hide" it? Or is there any other reason you wouldn't want people to use sertain characters/symbols in their passwords?

Hello, i am currently working on a project and i have been on google and nothing has helped i am trying to detect characters in the URL so for example XSS if someone typed in the URL:

home.php?=<script>document.cookie();</script>

OR

home.php?=<?php echo file_get_contents("document.txt", "a");

How would i be able to make a kind of firewall to detect this?   and if it does then redirect to another page.   Thanks.

Im not new to php but I am trying to think if this possible.

I want to write a php script that creates a div inside a div until lets say 10 divs are created.

I have been trying do while statements but them seem to place them underneth each other not within.

I want
<div id=one">
<div id=two">
<div id=three">
</div>
</div>
</div>

Only thing I can create is

<div id=one"></div>

<div id=two"></div>

<div id=three"></div>

Like I said  I dont even know if this is possible or if I am just retarded and can't think of a way to do it but it would be nice to see what others have to say about it.

hi php people,

I am wondering will  if the code below will work when I call $C->getafoo() will I get foo;  I keep getting an error at this point  return $this->A->a(); saying  the method is not there

Code: [Select]
class A{
  public function a(){
    return "foo";
  }
}

class B {
  public $A;

  function __construct($A) {
    $this->A = $A;   

  }

  public function geta(){
    return $this->A->a();
  }
}


class C extends B{
  public function getafoo(){
   return geta();
 }

}
$C = new C(new A());

echo $C->getafoo();

In php, which function is best used to act something like the sql "LIKE" command? and how would that function be used like?

Hi,

I am looking into a way of adding addons to a class I made.. I thought something like this would work, but not sure how to implement it:

Code: [Select]
<?php
class foo {
    function foobar($text) {
        $text = $text . 'b';
        return $text;
    }
}
class bar extends foo {
    function foobar($text) {
        $text = $text . 'c';
        return $text;
    }
}

$var = new bar();
$var->foobar('a'); // this would then return abc
?>

Now i want to be able to call up foo, and it calls the foobar of foo, and the foobar of bar.
is that possible?

hosh

I'm considering getting a VPS, but I'm not entirely sure what this would be able the handle. The specs doesn't look that good to me, but my friend swears it will handle running apache/php/mysql handling large websites and databases without a problem. I want to run multiple databases that just store statistics and I'm a bit worried about the RAM and the company doesn't even mention a cpu.

Here's the specs:
256MB RAM
300GB HDD
10Mbps unmetered
1 IP Address

My friend runs two counter-strike: source servers off his VPS (same stats).. so I'm actually considering this, but it just seems like it's not powerful enough.

Oh.. forgot the most important part.. it's only $9.

Just get started with OO in PHP. If I create an object while on one page and then call another page, can I still access that first object, or is it destroyed when the second page is called? For example, if I have on page1.php:

Code: [Select]
$obj = new $MyObject();
and then call page2.php, is it possible to still access $obj while on that page?

I have an issue with the below code

Code: [Select]
if ($gtype == "%24L" || $gtype == "$L")
The value actually starts with the dollar sign then L, but its being read as a variable that's not assigned so it showing as blank. so the question is how to I get to check and see if the value of gtype actually is $L in a way that it wont read $L as a variable and as a value instead?

Hello. I'm trying to pull information out of an xml file. However I'm a bit lost in getting the actual value.

Code: [Select]
$url="http://ws.audioscrobbler.com/2.0/?method=artist.getimages&artist=Dr%20Feelgood&limit=1&autocorrect=1&api_key=c107c9b5c09cb5693b6c19409dd984c1";

$xml = simpleXML_load_file($url,"SimpleXMLElement",LIBXML_NOCDATA);

$largesquare=$xml->images->sizes->size[2];
Is what I have but its not pulling the information. The above url will give you the link to a set xml file for this example. And I want to get the info for the

Code: [Select]
<size name="largesquare" width="126" height="126">http://userserve-ak.last.fm/serve/126s/43173899.jpg</size>
I'm sure I'm doing something wrong that's a simple fix but I am lost here. In the sizes there are 6 different size options each with different names and I have no idea how to pull the one with the correct name that I need.

Thank you to who ever can help me sort this out.

I am trying to make my database search only search where private = '$priiv'(Usually 0,1, or 2) but it does not work
Code: [Select]

$query_search = "SELECT * FROM users WHERE username LIKE '%$idea%' OR fname LIKE '%$idea%' OR lname LIKE '%$idea%' OR tags LIKE '%$idea%' AND private = '$priiv'";

What am i doing wrong?

I am trying to make it so that it will load if the site if the site is online(EG. $siteonline = 1), and so on. I can't seem to think of how I could do this so it will work from the very top of the page's html, to the very bottom.

Like the following code is meant to list all of the stuff in that database.
<?php
$list_q = mysql_query("SELECT * FROM settings") or die (mysql_error());
while($list_f = mysql_fetch_assoc($list_q)) {
}
?>

I have my page laid out like this..
<?php 
include "includes/connect.php";
include "includes/config.php"; 
?>
<?php
    $list_q = mysql_query("SELECT * FROM settings") or die (mysql_error());
    while($list_f = mysql_fetch_assoc($list_q)) {
?>
Html content etc..
<?php 
}
include 'includes/footer.php'; ?>

But if I do it that way, It only displays what is in footer.php.
